Description
Dans les moteurs à combustion interne, il est nécessaire de filtrer et de dégazer le carburant d'alimentation avant de l'introduire dans le carburateur, afin d'en éliminer toutes les particules d'impuretés qui y sont en suspension, ainsi que les bulles de gaz et d'air qui se dégagent du carburant par suite de l'élévation de température dans l'enceinte contenant le moteur.In internal combustion engines, it is necessary to filter and degas the fuel supply before introducing it into the carburetor, in order to remove all the particles of impurities which are in suspension there, as well as the bubbles gas and air released from the fuel as a result of the temperature rise in the enclosure containing the engine.
Jusqu'à présent, les constructeurs de voitures automobiles ont utilisé à cet effet deux dispositifs distincts, à savoir un filtre fin et un dispositif de dégazage avec ou sans tamis grossier disposés en série sur le circuit d'alimentation, entre la pompe à essence et le carburateur. Les filtres connus comprennent généralement un boîtier fixé sur le moteur et dans lequel est logée une cartouche filtrante. L'inconvénient d'un tel filtre est que sa cartouche filtrante doit être remplacée régulièrement avant qu'elle ne soit trop encrassée.So far, automobile manufacturers have used two separate devices for this purpose, namely a fine filter and a degassing device with or without coarse sieve arranged in series on the supply circuit, between the fuel pump and the carburetor. Known filters generally include a housing fixed to the engine and in which is housed a filter cartridge. The disadvantage of such a filter is that its filter cartridge must be replaced regularly before it becomes too dirty.
Par le brevet FR 2 580 190, on connaît un dispositif selon le préambule de la revendication 1, dans lequel le filtrage et le dégazage du carburant sont effectués dans un même boîtier. Mais, dans ce brevet, on suppose que tout le gaz arrivant avec le carburant traverse le cartouche filtrante et est évacué vers la tubulure de retour à travers le clapet, dès que celui-ci est soulevé par un excèdent de carburant se trouvant dans la cartouche, ce qui est faux car en raison du colmatage progressif de la cartouche, la majeure partie du gaz reste dans la chambre située à l'extérieur de la cartouche et ne peut en être évacuée. De plus, le dispositif selon ce brevet est incapable d'évacuer les gaz seuls puisque le clapet est taré pour être soulevé par le carburant liquide, les gaz s'échappant alors avec du carburant liquide.The patent FR 2 580 190 discloses a device according to the preamble of claim 1, in which the filtering and degassing of the fuel are carried out in the same housing. However, in this patent, it is assumed that all the gas arriving with the fuel passes through the filter cartridge and is evacuated towards the return pipe through the valve, as soon as the latter is lifted by an excess of fuel being in the cartridge. , which is wrong because due to the progressive clogging of the cartridge, most of the gas remains in the chamber located outside the cartridge and cannot be evacuated from it. In addition, the device according to this patent is unable to evacuate the gases alone since the valve is calibrated to be lifted by the liquid fuel, the gases then escaping with liquid fuel.
Le brevet DE 3 540 260 remédie bien à cet inconvénient par l'utilisation d'un clapet qui, en position de repos, est appliqué sur un siège présentant des saillies qui définissent des passages à travers lesquels le gaz seul peut passer vers la tubulure de retour. Toutefois, l'échappement des gaz ne peut s'effectuer que lorsque le clapet est en position de repos, c'est-à-dire lorsque le dispositif ne fonctionne pas. Dès que la pompe débite, le clapet est soulevé contre un obturateur, de sorte que le passage des gaz est coupé.Patent DE 3,540,260 remedies this drawback well by the use of a valve which, in the rest position, is applied to a seat having projections which define passages through which only gas can pass to the return line. However, the escape of gases can only take place when the valve is in the rest position, that is to say when the device does not work. As soon as the pump delivers, the valve is lifted against a shutter, so that the gas flow is cut off.
La présente invention a pour but de remédier aux inconvénients des dispositifs de filtrage et de dégazage de la technique antérieure connue, et concerne à cet effet un dispositif de filtrage et de dégazage selon la partie caractérisante de la revendication 1.The object of the present invention is to remedy the drawbacks of the filtering and degassing devices of the known prior art, and for this purpose relates to a filtering and degassing device according to the characterizing part of claim 1.
D'autres caractéristiques de l'invention font l'objet des revendications suivantes.Other features of the invention are the subject of the following claims.
Le dispositif selon l'invention permet donc de regrouper en une seule unité les deux fonctions de filtrage et de dégazage, et de gagner ainsi une place précieuse autour du moteur. Le dispositif selon l'invention peut être fixé à la place du filtre à essence traditionnel.The device according to the invention therefore makes it possible to combine the two filtering and degassing functions in a single unit, and thus gain precious space around the engine. The device according to the invention can be fixed in place of the traditional fuel filter.
La cuve et le corps de couvercle peuvent être réalisés en un matériau résistant et bon marché, par exemple en une matière synthétique résistante aux hydrocarbures. Ils pourront alors être soudés entre eux de manière à assurer une bonne étanchéité de l'enceinte intérieure. En variante, la cuve peut être réalisée en matériau métallique, et sertie d'une manière étanche sur le corps. Le choix d'un matériau métallique conducteur ou synthétique isolant de la chaleur ambiante dépend de la configuration du moteur ou du véhicule.The tank and the cover body can be made of a resistant and inexpensive material, for example a synthetic material resistant to hydrocarbons. They can then be welded together so as to ensure a good seal of the inner enclosure. Alternatively, the tank can be made of metallic material, and crimped in a sealed manner on the body. The choice of a conductive or synthetic metallic material insulating from ambient heat depends on the configuration of the engine or the vehicle.
Comme cartouche filtrante, on pourra utiliser un papier standard du commerce. Il en résulte que l'on pourra fabriquer le dispositif selon l'invention à un prix suffisamment bas pour que l'on puisse le jeter et le remplacer par un dispositif neuf, dès que sa cartouche filtrante est encrassée.As a filter cartridge, standard commercial paper may be used. As a result, the device according to the invention can be manufactured at a sufficiently low price that it can be discarded and replaced by a new device, as soon as its filter cartridge is dirty.
Un mode de réalisation de l'invention sera à présent décrit en regard des dessins annexés dans lesquels:
- La figure 1 est une vue en coupe selon un plan diamétral du dispositif de filtrage et de dégazage;
- La figure 2 est une vue à plus grande échelle d'un détail de la figure 1;
- La figure 3 est une vue en coupe suivant la ligne III-III de la figure 1; et
- La figure 4 est une vue en coupe suivant la ligne IV-IV de la figure 2.
- Figure 1 is a sectional view along a plane diametral of the filtering and degassing device;
- Figure 2 is an enlarged view of a detail of Figure 1;
- Figure 3 is a sectional view along line III-III of Figure 1; and
- Figure 4 is a sectional view along line IV-IV of Figure 2.
Le dispositif illustré sur les figures comprend un boîtier formé d'une cuve de décantation 10 et d'un corps de couvercle creux 12, avantageusement réalisés en une matière synthétique résistant aux hydrocarbures. La cuve peut également être en métal. La cuve et le corps de couvercle sont soudés bord à bord, par exemple par le procédé par rotation, ou sertis dans le cas d'une cuve métallique.The device illustrated in the figures comprises a housing formed by a settling
La cuve présente en son fond des nervures 14 sur lesquelles repose un filtre désigné dans son ensemble par la référence 16. Le filtre comprend une paroi latérale cylindrique 18 en papier filtrant de faible porosité, avantageusement pliée en accordéon pour en augmenter la surface latérale, et qui est coiffée à ses extrémités par deux flasques 20, 22 fixés hermétiquement.The tank has ribs at its bottom 14 on which a filter rests designated as a whole by the
Avec le corps de couvercle viennent de moulage une tubulure d'arrivée 24 pour le carburant qui est refoulé par la pompe à essence et une tubulure de sortie 26 reliée au carburateur. La tubulure d'arrivée est dirigée radialement vers l'axe du dispositif, tandis que la tubulure de sortie est disposée selon ledit axe, et elle se prolonge intérieurement par une canule 28 qui traverse avec étanchéité le flasque supérieur 20 du filtre et plonge jusqu'à une faible distance au-dessus du flasque inférieur 22. La canule traverse le flasque supérieur en son centre et de ce fait elle maintient le filtre en position coaxiale par rapport aux parois latérales de la cuve et du corps de couvercle.With the cover body come molding an
Sur la partie de la canule située au-dessus du filtre vient de moulage un déflecteur 30 de forme concave (voir également la figure 3), dont la concavité est tournée vers la tubulure d'arrivée 24, de manière que le jet incident du carburant vienne s'y briser.On the part of the cannula located above the filter is molded a
Le corps de couvercle comprend également à sa partie la plus haute un orifice 32 autour duquel vient de moulage une tubulure 34 pour le retour du carburant ou du gaz vers le réservoir. Cet orifice est obturé par une plaquette 36 percée de trous 38 pour le passage du carburant vers la tubulure de retour 34. La plaquette sert de siège pour un clapet 40, en position ouverte, qui dans la figure 2, est réalisé sous forme de coupe, mais qui peut avoir toute autre forme appropriée. Le clapet peut se débattre dans un alésage cylindrique 42 d'axe vertical et de diamètre adapté à celui du clapet. Il est normalement appliqué contre une saillie 44 formée sur la face supérieure de la plaquette, par un ressort précontraint 46. Celui-ci prend appui d'autre part dans une gorge circulaire 47 formée autour d'une portion tubulaire 52 servant de second siège pour le clapet, lorsque celui-ci est repoussé vers le haut par le carburant liquide, comme on l'expliquera par la suite. L'alésage 48 de la portion tubulaire 52 communique avec la tubulure de retour 34. L'alésage 42 présente une pluralité de rainures axiales 50 de longueur telle que lorsque le clapet est appliqué sur la saillie 44, une communication de section constante subsiste entre les trous 38 et l'alésage 48, par l'intermédiaire des rainures.The cover body also comprises, at its uppermost part, an orifice 32 around which a
Le clapet présente en son centre un petit trou calibré 54 par lequel un faible débit de fuite de carburant liquide peut s'échapper lorsque le clapet est dans sa position haute.The valve has in its center a small calibrated hole 54 through which a low liquid fuel leakage rate can escape when the valve is in its high position.
On expliquera à présent le fonctionnement du dispositif de filtrage et de dégazage selon l'invention: le mélange carburant liquide et gaz arrive par la tubulure d'arrivée 24 au-dessus du filtre 16 et se heurte au déflecteur 30. Il se produit à ce niveau une première séparation entre la phase liquide et la phase gazeuse du carburant. Le gaz remonte vers la paroi supérieure du corps de couvercle, tandis que le carburant liquide descend lentement le long de la paroi du papier filtre 18 qu'il traverse pour pénétrer à l'intérieur du filtre. Dans cette deuxième phase, il abandonne à l'extérieur du filtre:
- les bulles de gaz encore en suspension qui remontent vers le sommet du boîtier,
- l'eau éventuelle qui se décante dans la cuve, et
- les impuretés solides diverses qui se déposent sur le papier filtrant et sous le flasque inférieur du filtre.
- gas bubbles still in suspension which rise towards the top of the housing,
- any water that settles in the tank, and
- various solid impurities which are deposited on the filter paper and under the lower flange of the filter.
C'est une essence considérablement ralentie et dégazée qui vient remplir le fond du filtre, d'où elle est refoulée par la canule 28 vers le carburateur.It is a gasoline considerably slowed down and degassed which comes to fill the bottom of the filter, from where it is pushed back by the
Pendant ce temps, la couche de gaz qui s'est formée à la partie supérieure du boîtier, s'échappe normalement vers la tubulure 34 de retour au réservoir, en passant par les trous 38, puis en contournant, par l'intermédiaire des rainures 50, le clapet qui est alors maintenu appliqué contre son siège 44 par le ressort taré 46 et enfin à travers l'orifice de retour 48.During this time, the layer of gas which has formed at the upper part of the housing, normally escapes towards the
Lorsque tout le gaz a été évacué, l'essence qui continue à arriver emplit tout le boîtier, et cherche à s'échapper par le même chemin que le gaz. Mais en raison de sa viscosité relativement élevée, elle n'arrive pas à s'écouler, les rainures 50 lui opposant une grande résistance (perte de charge). La pression du carburant liquide augmente jusqu'au moment où celui-ci soulève le clapet 40 à l'encontre de la force du ressort 46, et l'applique contre la butée annulaire 52. L'orifice de retour 48 est alors obturé. Le débit de carburant vers le réservoir est limité par le calibrage du trou central 54. Ce débit crée en aval du clapet une perte de charge qui maintient le clapet fermé.When all the gas has been evacuated, the gasoline which continues to fill fills the whole case, and tries to escape by the same path as the gas. But due to its relatively high viscosity, it cannot flow, the
Le clapet ne pourra se rouvrir que lorsque l'action du ressort contrebalancera la pression qui s'exerce sur lui. Ceci se produira lorsqu'un matelas d'air d'épaisseur suffisante se sera reformé sous le clapet. Celui-ci reviendra alors à sa position ouverte et une nouvelle phase de dégazage se produira.The valve can only reopen when the action of the spring counterbalances the pressure exerted on it. This will happen when an air mattress of sufficient thickness has reformed under the valve. This will then return to its open position and a new degassing phase will occur.
En résumé, le passage résiduel formé lorsque le clapet est en position ouverte doit permettre au gaz de s'écouler sans donner naissance à une perte de charge, tandis que le carburant liquide doit créer une perte de charge. On pourra déterminer la section de passage en utilisant un clapet échantillon ayant des mesures approchées.In summary, the residual passage formed when the valve is in the open position must allow the gas to flow without giving rise to a pressure drop, while the liquid fuel must create a pressure drop. We can determine the passage section using a sample valve with approximate measurements.
